Service 01

AI Development

Intelligent systems that earn their place in the product. Not bolted on for a pitch deck. Built to solve real problems your users actually have.

What usually goes wrong

Most AI features are a wrapper around an API call with no thought given to reliability, cost, or user experience. They hallucinate, they are slow, and they break silently. Your users lose trust before the feature has a chance to prove itself. AI done badly is worse than no AI at all.

This service is right for you if
  • You have a product where AI could genuinely improve the user experience
  • You need intelligent automation that works reliably at scale
  • You want to integrate LLMs or custom models without the hype and guesswork
  • You have been burned by an AI feature that was slow, expensive, or inaccurate
Project showcase

What you actually get

Purpose-built intelligence

AI features designed around your actual use case. Not a demo that works in a slide deck and breaks in production.

Optimised for speed and cost

Model selection, prompt engineering, and caching strategies that keep inference fast and your bill predictable.

Evaluated before it ships

Every AI feature is tested against edge cases, adversarial inputs, and real-world data before your users see it.

Monitoring from day one

Drift detection, accuracy tracking, and usage analytics so you know when the model is helping and when it is not.

Deliverables

Production AI pipeline

End-to-end inference system, deployed and monitored in your environment.

Model evaluation report

Accuracy benchmarks, latency metrics, and cost projections documented.

Integration documentation

API contracts and usage guides your team can build on top of.

30 days post-launch support

Model tuning, edge case fixes, and performance optimisation covered.

Service 02

Web Development

Frontends that feel instant. Backends that stay calm under traffic. Full-stack web builds designed for performance, scale, and the kind of polish users notice.

What usually goes wrong

Web apps built without architecture age badly. They work at launch and slow down at scale. The frontend feels sluggish, the backend chokes under load, and every new feature takes twice as long as the last one. A web build that was not designed for growth becomes your most expensive technical debt.

This service is right for you if
  • You need a performant web application that handles real users and real data
  • You have a frontend team that needs a solid backend partner or vice versa
  • Your current web stack is slowing your team down and frustrating your users
  • You want clean API design and documentation someone else can actually maintain

What you actually get

Security baked in

Auth, permissions, data validation, and OWASP basics are part of the build. Not a review note at the end.

Load-tested before launch

We simulate real traffic before your users create it. You know the limits before they become problems.

API documentation

Every endpoint documented. Your frontend team, future hires, and integrations all work from the same clear source.

Cloud-native from day one

Containerised, deployable, and infra-agnostic. AWS, Azure, or whatever comes next. No vendor lock-in.

Deliverables

Production web deployment

Live environment with staging, logging, and monitoring.

API documentation

Swagger or equivalent. Every route, every expected response.

Load test report

Documented limits and performance benchmarks.

Security review summary

What we checked, what we found, and what we fixed.

Service 03

Mobile Apps

Apps that feel light to the user and run heavy under the hood. Cross-platform without the cross-platform compromise.

What usually goes wrong

Most mobile builds feel like web pages dressed up. Slow load times, janky transitions, and a codebase that needs rebuilding when you want a new feature. Your users notice. Your retention numbers show it.

This service is right for you if
  • You have a product idea that lives on a phone
  • You need iOS and Android without two separate budgets
  • Your last mobile build felt sluggish and your team knows it
  • You want real device testing before any user ever opens it
Project showcase

What you actually get

Native-level performance

Flutter and React Native done properly. Not ported from a website. Optimised for the device from day one.

One codebase, both platforms

iOS and Android from a single codebase. Half the maintenance, full coverage. No feature gaps between platforms.

Real device testing

Tested on actual hardware across screen sizes and OS versions before anything goes near your users.

Scalable data layer

State management and API design built to handle 10 users and 100,000. No rewrites when traction hits.

Deliverables

Production-ready app bundle

iOS and Android packages, App Store ready.

QA report and test coverage

Full device matrix test results. Nothing untested ships.

Code handoff documentation

Your next developer can inherit this cleanly.

30 days post-launch support

Bugs, edge cases, and store submission issues covered.

Service 04

MVP Development

Four weeks from idea to live product. Scoped to prove the point. Built to grow past it. Investor-friendly from the very first commit.

What usually goes wrong

MVPs built to be perfect before launch never launch. Scope creep kills momentum. Three months becomes six. Your window closes while you are still in Figma. The right MVP is the smallest version that proves you are onto something real.

This service is right for you if
  • You have a validated idea and need something users can actually touch
  • You are raising a seed round and need a live product in the room
  • You want to test a hypothesis before committing a bigger budget
  • You have been burned by slow, scope-creeping agency builds before
The 4-week breakdown
Wk 1

Scope and architecture

Define the minimum that proves the point. Sprint planning, tech decisions, design system.

Wk 2

Core build

Primary user flows built, tested, and deployed to staging. You see working software, not wireframes.

Wk 3

Integrate and polish

Payments, auth, third-party APIs wired up. Edge cases handled. Performance tuned.

Wk 4

Launch prep

App store submissions, monitoring, analytics, documentation. Handed over production-ready.

What you actually get

Scoped to what matters

We push back on anything that does not prove the core idea. Smaller scope is not a shortcut, it is a strategy.

Analytics from launch

You know who is using it, how, and where they stop. Real data from day one so iteration is informed not guessed.

Built to grow

Architecture that does not need rebuilding at 10x users. The MVP is lean, not fragile.

Investor-ready

Clean code, documented decisions, and a product that reflects well when investors or acquirers look under the hood.

What is included

Live, deployed product

Not a staging environment. Not a demo. A live URL your users can visit.

Analytics setup

User tracking, event logging, and a dashboard you can actually read.

Full source code and docs

Everything you own, properly documented, properly yours.

30-day post-launch support

We stay reachable. Bugs and questions answered without a new contract.

Service 05

UX/UI Design

Design that is tested before it is built. Research-led, conversion-aware, and built to make your developers' lives easier, not harder.

What usually goes wrong

Design without research is decoration. Pretty screens that nobody tested. Handoffs that leave developers guessing. Components that look different on every page. Your product feels inconsistent, your users feel lost, and your team wastes weeks rebuilding what should have been right the first time.

This service is right for you if
  • You are building a new product and need design from the ground up
  • Your current UI feels inconsistent and your users are telling you
  • You want a design system your developers can actually implement cleanly
  • You need user research and testing before committing to a full build
Project showcase
Project showcase

What you actually get

Research before pixels

User interviews, competitor analysis, and journey mapping before a single screen is designed. Decisions backed by evidence, not taste.

A real design system

Reusable components, consistent spacing, colour tokens, and typography rules. Your product looks cohesive and your developers move faster.

Tested with real users

Interactive prototypes tested with actual users before development begins. You fix problems in Figma, not in code.

Developer-ready handoff

Annotated designs, interaction specs, and responsive breakpoints. Your engineering team inherits clarity, not ambiguity.

Deliverables

Full UI design in Figma

Every screen, every state, every breakpoint. Organised and annotated.

Component library

Reusable design system components your developers can map directly to code.

User testing report

Findings from usability testing with real users. What worked, what did not.

Interaction specifications

Animations, transitions, and micro-interactions documented for development.

Service 06

Custom Build

Complex problems require tailored solutions. Full-scale platforms designed specifically for your unique operational requirements and business goals.

What usually goes wrong

Off-the-shelf software rarely fits complex business models perfectly. Workarounds accumulate, efficiency drops, and eventually the system dictates how you work instead of the other way around. Custom software built poorly just creates a more expensive set of constraints.

This service is right for you if
  • Your operational complexity has outgrown SaaS tools and spreadsheets
  • You are building a specialized platform that requires bespoke architecture
  • You need deep integrations across multiple legacy and modern systems
  • Your business logic is your competitive advantage and needs custom code
Project showcase

What you actually get

Bespoke architecture

Systems designed specifically for your data models and workflows. No forcing round pegs into square holes.

Seamless integration

Connecting your new custom platform with the tools your team already uses, without breaking existing processes.

Enterprise-grade security

Custom builds mean custom threat models. Security is designed around your specific vulnerabilities and compliance needs.

Unconstrained scalability

When your business scales, your software scales. No artificial usage caps or sudden expensive enterprise tiers.

Deliverables

Production software platform

Fully deployed, custom-built application tailored to your specifications.

Comprehensive technical docs

Architecture diagrams, API documentation, and database schemas.

Automated test suite

Unit, integration, and end-to-end tests to ensure long-term stability.

30 days post-launch support

Ongoing monitoring and stabilization during the critical launch phase.

FAQ

Questions about our services

Anything else on your mind, just book a call. We would rather answer you directly than have you guess.

Yes, and most projects do. An MVP usually includes both a mobile app and a backend. A custom build might include AI, a backend, and a frontend. We scope the whole thing together so nothing gets siloed or duplicated.

We do not publish a minimum but we are not a freelancer rate shop. We work best with founders and teams who are serious about building something with a real budget and a real timeline. If you are unsure whether we are right, just book a call and we will be honest.

We can work fixed-price or on a flexible engagement depending on how well-scoped the project is at the start. We always give you a written scope with costs before any work begins. You know exactly what you are paying for before we start.

We scope tightly upfront specifically to protect against this. If requirements genuinely change, we have an honest conversation about what that means for timeline and cost. No surprise invoices, no resentment. Just a clear discussion.

Yes. Many clients move from a project engagement into an ongoing partnership for DevOps, new features, and architecture decisions. We find it works better for everyone when the same team builds and maintains rather than handing over to someone who was not there for the original decisions.

An MVP runs four weeks. A custom build depends on complexity and is always scoped before we start. Backend projects typically run four to eight weeks. We will always give you a timeline in writing before any work begins.
